Intraoperative Neuromonitoring (IONM) and Bipolar Electrocautery (BE) During Axillary Lymph Node Dissection (ALND)
Sponsor: University of Cincinnati
Summary
The purpose of this study is to determine whether the implementation of existing neurosurgical techniques of intraoperative neuromonitoring (IONM) and the replacement of monopolar electrocautery with bipolar electrocautery (BE), during ALND, will improve the early identification of nerves that have been implicated in the cause of neuropathically-mediated post-surgical pain syndrome (PSPS).
Official title: Feasibility of Using Intraoperative Neuromonitoring (IONM) and Bipolar Electrocautery (BE) During Axillary Lymph Node Dissection (ALND) to Provide Early Identification and Protection of the Intercostalbrachial Nerve (ICBN), Medial Branch Cutaneous Nerve (MBCN), and Their Branches

IONM procedure
This study is designed to determine the feasibility of using IONM to identify and confirm the location of the ICBN and MBCN, and their branches, during ALND breast surgery. Once the patient is asleep after the induction of anesthesia, electrodes will be placed by the IONM technician. Monitoring electrodes will be placed in the patient's scalp and along the cervical and brachial nerves and stimulating elecctrodes will be placed to stimulate the median and ulnar nerves. Although IONM techniques have been used in other specialties to monitor a variety of different nerves to make surgery safer, monitoring of the ICBN and MBCN has never been performed. This pilot study is to determine the stimulating and recording parameters for these nerves by using the known parameters for the median and ulnar nerves as a starting point. Continuously monitoring the function of the median and ulnar nerves will also provide an integrity check of the recording system during surgical cases.
